I'm completely new to DWC, and I need to know if this tentative feeding schedule is good or how I could adjust it. I'm using organic bloom nutes, organic nettle/bramble compost tea (pasturized), and plain hard-water from the tap. (Boiled then left to cool an evaporate some of the crap chems)
Don't know much about using tea but your feeding should be adjusted to individual plants. There is a great sticky in hydro section about how to determine nutrient strength. Do you have a ppm/ec meter? If not it is very impt for dwc because your ph/ppm can change from day to day if the plant is getting to much or to little nutrients. For hydroponics and dwc especially a good quality ph/ppm meter is critical.
